RT7257AHZSP Product Details

RT7257AHZSP Overview


A Cut Tape (CT) package is used in this voltage regulator to optimize performance. This harley voltage regulator has 8 terminations. This harley voltage regulator is available in the 8-SOIC (0.154, 3.90mm Width) Exposed Pad package for the purpose of space saving. There are 1 outputs on DC DC switching regulator. The adjusting voltage regulator generates Adjustable output. The voltage regulator 12v fits the Surface Mount mounting hole. In order for it to operate properly, dc to dc voltage regulator's operating temperature should be at -40°C~85°C TA. 340kHz is the switching frequency of this DC-DC switching regulator. The voltage regulator can be operated with a voltage as low as 4.5V as an input voltage. In this adjusting voltage regulator, the output voltage (Min/Fixed) equates to 0.8V. The output current of 3A makes dc to dc voltage regulator feature maximum design flexibility. As far as the voltage input is concerned, DC DC switching regulator can accept up to 18V. This voltage regulator is included in the Switching Regulator or Controllers subcategory. At 15V volts, voltage regulator can provide voltage. For switching regulator operation, 8 pins are used. In order to use this voltage regulator 12v at its full potential, the output voltage should be kept at at least 800mV. As a result, it is able to provide adjusting voltage regulator a maximum output voltage of 15V.
